  A. By default,Netflow records bidirectional IP traffic flow.
  B. Netflow answers questions regarding IP traffiC. who, what, where, when, and how
  C. Netflow accounts for both transit traffic and traffic destined for the router.

  B. Netflow answers questions regarding IP traffiC. who, what, where, when, and how
  C. Netflow accounts for both transit traffic and traffic destined for the router.
  D. Netflow returns the subinterface information in the flow records.

• Question 833:

  Refer to exhibit.

  

  Which conclusion is true?

  A. CT0 TE LSP can preempt CT1 TE. CT1 TE LSP cannot preempt CT0, except CT1 TE LSPs that corresponds to TE Class 0.
  B. CT0 TE LSP can preempt a CT1 TE LSP, but not vise versa. A CT1 TE LSP with a better priority can still preempt a CT1 TE LSP with worse priority.
  C. CT1 TE LSP can preempt some CT0 TE LSPs and vice versa however other TE LSPs cannot preempt CT1 TE LSPs that corresponds to TE Class 0.
  D. CT1 TE LSP can preempt a CT0 TE LSP, but not vice versa. A CT0 TE LSP with a better priority can still preempt a CT0 TE LSP with worse priority.
  C. CT1 TE LSP can preempt some CT0 TE LSPs and vice versa however other TE LSPs cannot preempt CT1 TE LSPs that corresponds to TE Class 0.

• Question 834:

  Typical ADSL broadband Internet access requires a username and password to be entered on end-user PC connected to the ADSL modem in order for the end user to gain access to the Internet. If a Cisco ADSL router is used instead of an ADSL modem, what functionality is required on the Cisco ADSL router so the end-user connected to the Cisco ADSL router can access the Internet without entering a username and password?

  A. Route Bridge Encapsulation (RBE)
  B. PPPoA
  C. Integrated Routing and Bridging (IRB)
  D. AAA
  E. PPPoE client
  E. PPPoE client

• Question 835:

  DRAG DROP Refer to the exhibit.

  

  When integrating 2G or 3G and 4G functions in one node as this scenario shows, drag and drop the functional element on the left onto the correct numbered item from the exhibit on the right.

• Question 836:

  What step must be performed before creating multiple named-SDRs?

  A. Connect all three consoles on the RP faceplate on the router.
  B. Configure the system to boot into Single Owner Single Tenant (SOST) mode.
  C. Boot the system in Single Owner Multiple Tenant (SOMT) mode.
  D. Delete the default SDR after verifying all nodes are in operational state.
  D. Delete the default SDR after verifying all nodes are in operational state.

• Question 837:

  Which of the following IOS features can prevent IP spoofing attacks?

  A. Unicast Reverse Path Forwarding (uRPF)
  B. MPLS traffic Engineering
  C. Cisco Express Forwarding
  D. PPP over Ethernet
  E. IS-IS routing
  A. Unicast Reverse Path Forwarding (uRPF)

• Question 838:

  DRAG DROP

  Drag and drop the MPLS Inter-AS models from the left onto the correct characteristics on the right.

  Select and Place:

  

  

• Question 839:

  Which description of the Russian Doll Model is true?

  A. RDM provides bandwidth sharing while providing bandwidth isolation and protection against QoS degradation, and also provides service differentiation for high-priority, normal- priority and best-effort priority services
  B. RDM matches simple bandwidth control policies setting individual bandwidth constraint for a given class type and simultaneously limit the aggregate of reserved bandwidth across all class types
  C. RDM can be used simultaneously to ensure bandwidth efficiency and to protect against QoS degradation of all class types, whether preemption is used or not
  D. RDM guarantees a predefined amount of bandwidth for each type and at the same time allows the bandwidth sharing by defining two pools for every class type: private pool (guaranteed bandwidth) and common pool (bandwidth shared between all class types)
  C. RDM can be used simultaneously to ensure bandwidth efficiency and to protect against QoS degradation of all class types, whether preemption is used or not

• Question 840:

  Drag and drop the OSPFv2 Loop-Free Alternate Fast Reroute policy attributes from the left onto the prioritized order for the possible repair candidates in the right when a primary path fails.
